Solar storm watch issued

The strongest solar storm in seven years is on its way to Earth, courtesy of a giant flare that erupted on the Sun on Sunday.

The National Oceanic and Atmospheric Administration's Space Weather Prediction Center has posted a watch for a geomagnetic storm which could arrive 9 a.m. Tuesday "with possible impacts to navigation, the power grid and satellites."

NOAA said the flare produced a“coronal mass ejection,” whichis a burst of charged particles and magnetic field that streamed out from the sun at about four million miles an hour.
